Abstract

The present invention relates to a method and an apparatus for transmitting/receiving data, and a method for a user equipment transmitting data, according to one embodiment of the present invention, comprises: a step of determining conditions for determining whether a condition for transmitting short data is satisfied, when data to be transmitted is generated; and a step of including the data to be transmitted in a radio resource control (RRC) connection setup completion message and transmitting same, when the condition for transmitting the short data is satisfied. According to one embodiment of the present invention, the problem of network overload can be prevented by reducing signaling overhead when processing small packets, which are generated intermittently, in the mobile communication system, and an apparatus and a method for enhancing battery performance in the user equipment can be effectively provided.

Claims

1. A method for transmitting data by a terminal in a wireless communication system, the method comprising:

identifying whether uplink data occurs or not;

determining whether a terminal is in an idle state or not;

transmitting, to a base station, a radio resource control (RRC) connection request message in case the uplink data occurs and the terminal is in the idle state;

receiving a RRC connection setup message in response to the RRC connection request message; and

transmitting a RRC connection setup complete message comprising a non-access stratum (NAS) message, the NAS message including the uplink data,

wherein the NAS message is integrity protected and the uplink data included in the NAS message is encrypted.

2. The method of claim 1, wherein:

the idle state is an evolved packet system (EPS) connection management idle (ECM-IDLE) state, and

wherein the uplink data is associated with an EPS bearer.

3. The method of claim 1, wherein the uplink data is included in dedicatedInfoNAS in the RRC connection setup complete message.

4. The method of claim 1, wherein the RRC connection setup complete message further comprises mobility management entity (MME) information.

5. The method of claim 4, wherein the MME information comprises routing information for determining MME to which the base station routes the NAS message.

6. The method of claim 1, wherein the RRC connection setup complete message is transmitted in case a predefined condition is fulfilled.

7. A terminal for transmitting data in a wireless communication system, the terminal comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to;

identify whether uplink data occurs or not,

determine whether a terminal is in an idle state or not,

transmit, to a base station, a radio resource control (RRC) connection request message in case the uplink data occurs and the terminal is in the idle state,

receive a RRC connection setup message in response to the RRC connection request message, and

transmit a RRC connection setup complete message comprising a non-access stratum (NAS) message, the NAS message including the uplink data,

wherein the NAS message is integrity protected and the uplink data included in the NAS message is encrypted.

8. The terminal of claim 7, wherein:

the idle state is an evolved packet system (EPS) connection management idle (ECM-IDLE) state, and

wherein the uplink data is associated with an EPS bearer.

9. The terminal of claim 7, wherein the uplink data is included in dedicatedInfoNAS in the RRC connection setup complete message.

10. The terminal of claim 7, wherein the RRC connection setup complete message further comprises mobility management entity (MME) information.

11. The terminal of claim 10, wherein the MME information comprises routing information for determining MME to which the base station routes the NAS message.

12. The terminal of claim 7, wherein the RRC connection setup complete message is transmitted in case a predefined condition is fulfilled.

13. A method for receiving data by a network device in a wireless communication system, the method comprising:

receiving, from a terminal, a radio resource control (RRC) connection request message in case uplink data occurs and the terminal is in an idle state;

transmitting a RRC connection setup message in response to the RRC connection request message; and

receiving a RRC connection setup complete message comprising a non-access stratum (NAS) message, the NAS message including the uplink data,

wherein the NAS message is integrity protected and the uplink data included in the NAS message is encrypted.

14. The method of claim 13, wherein the idle state is an evolved packet system (EPS) connection management idle (ECM-IDLE) state, and

wherein the uplink data is associated with an EPS bearer.

15. The method of claim 13, wherein the uplink data is included in dedicatedInfoNAS in the RRC connection setup complete third message.

16. The method of claim 13, wherein the RRC connection setup complete message further comprises mobility management entity (MME) information.

17. A network device for receiving data in a wireless communication system, the network device comprising:

a transceiver; and

at least one processor coupled with the transceiver and configured to;

receive, from a terminal, a radio resource control (RRC) connection request message in case uplink data occurs and the terminal is in an idle state,

transmit a RRC connection setup message in response to the RRC connection request message, and

receive a RRC connection setup complete message comprising a non-access stratum (NAS) message, the NAS message including the uplink data,
